Patented Jan. 16, 1917..

To all whom it may concern.-

Be it known that 1, CHARLES MOCARTER, a citizen of the United States,and a resident of Decatur, in the county of Macon and State of Illinois,have invented a new and Improved Car-Mover, of which the following is afull, clear, and exact description.

My invention relates to a contrivance whereby cars can be easily movedon the tracks, and the object thereof is to provide a simple,inexpensive and efficient device for the purpose stated.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

1n the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of my invention as applied to a car wheelto move a car; Fig. 2 is an end elevation, the actuating lever beingshown in section; Fig. 3 is a fragmentary rear elevation similar to thatshown in Fig. 2 but illustrating the contrivance in the position whenthe operating lever is moved upward or when the device is disengagedfrom the car wheel; Fig. 4 is a top plan view; Fig. 5 is a sideelevation of the upper part of the device from the side opposite to whatis shown in Fig. 1; Fig. 6 is a perspective view of the cam; Fig. 7 is aperspective View of the wheel and clamp which carries the cam; Fig. 8 isan elevation of a modified structure of the wheel clamp; and Fig. 9 isan elevation of a further modification of the wheel clamp.

Referring to the drawings, 10 is the car riage truck or frame which hasspaced flanged rollers 11 at the base for riding on a rail 12 of thetrack. The carriage frame 10 at the top thereof has a bearing 13disposed transversely of the frame for accommodating a double crankshaft 14-, the two cranks 15 and 16 respectively being at the ends ofthe shaft and directed oppositely. The crank 16 has a socket for an endof an operating lever 17 whereby the shaft 14 may be rocked in thebearing.

A link 18 connects the lug 19 of a cam or jaw 20 to the crank 15. Thejaw is mounted to revolve on a trunnion 21 provided at one end of aclamp 22. The clamp extends transversely of the frame and has at theother end a stationary jaw 23 whereat the clamp is suspended by a link24 from a lug 26 extending from the crank 16. The link passes through aslot in the lug. The clamp 22 is bent at the jaw 20 to clear the flangeof the car wheel 27. The frame 10 has a boss 28 constituting a guide forthe clamp 22, the curvature of which is such as to maintain the clamp inclose proximity to the car wheel when said clamp is moved by the rockingof the crank shaft 14:.

The clamp 22 is balanced on a link 29 which is suspended from one end ofa lever 30 fulcrumed between its ends on a cap of the bearing 13. Thelink 2-1 has a collar 31 adapted to engage the lug 26 when the clamp 22is moved upwardly by the lever 30 where by the upward movement of thefixed jaw is arrested, while the movable jaw is free to move;consequently the distance between the two jaws is increased and thedevice may be brought into engagement with the car wheel. In releasingthe lever 30, gravity brings the clamp into engagement with the sides ofthe car wheel.

'Bymovingthe actuating lever 17 down, the grip of the clamp on the wheelis increased, and, consequently, the car wheel is caused to move by thedownward displacement of the actuating lever. As the actuating lever 17is moved upward, the hold of the clamp on the car wheel is released, dueto the fact that the lug 26 is shorter than the crank 15, consequently,the distance between the fixed and movable jaws is increased during theinitial upward move- 1116111 of the lever 17. A reverse initial movementof the lever 17 shortens the distance bet-ween the fixed and the movablejaw for the same reason and causes the clamp to grip the sides of thewheel.

It will be noted that the clamp 22 has lugs 32 and 33 which are engagedby the links 24 and 29 respectively. The clamp has 7 be operated fromthe crank and the other from the lug 26.

In Fig. 9 the clamp 22 is shown provided with twofixed jaws 23, theengagement of the wall with the said jaw being obtained by the unequaldisplacement of the two fixed jaws through the medium of the crank 15and'the lug 26. It will be noted that the operating lever 17 is outsideof the track,

consequently it may be operated without any hindrance where two cars arecoupled, for there willbe plenty of room to move the lever due to thefact that said arm is outside of the track.

I claim:

1. A car mover comprising a frame, a lever fulcrumed onthe frame, aclamp for engaging the sides of a car wheel operable by the movement ofthe lever, and a boss extending from the frame for guiding the movementof the clamp.

2. A car mover comprising a frame, rollers therefor for riding on arail, a double crank shaft mounted to rock in the frame, the two cranksbeing directed oppositely, one of said cranks having a socket, a leverengaging said socket whereby the shaft may be rocked, a lug extendingfrom said socket having crank in a direction parallel to the secondcrank, said lug being shorter than said second crank, and a. clampsuspended from said lug and second crank to engage or disengage thesides of a car wheel when said shaft is rocked.

3. A car mover comprising a frame, rollers therefor for riding on arail, a hearing at the top of the frame disposed transversely thereof, adouble crank shaft in said bearing, the two cranks being disposedoppositely, one of said cranks having a socket, a lever engaging saidsocket, a lug extending from said crank having a socket in the samedirection withthe second crank. said lug being of a shorter length thansaid second crank, a clamp for engaging the sides of a car wheel, linksconnecting said clamp to the lug and said second crank, and means formoving the clamp between the lug and the second crank.

. 4:. A car mover comprising a frame, rollers therefor for riding on arail, a clamp for engaging the sides of a car wheel, a lever fulcrumedon the frame, and means for connecting the lever to the ends of theclamp so that one end of the clamp has a greater movement than the otherduring the movement of the lever, whereby said clamp may be caused toengage or disengage the car wheel.

5. A car mover comprising a frame, a movable clamp having a fixed jawand a movable aw for engaging the sides of a car wheel, a rocking shafton the frame engaging the fixed and movable jaws of the clamp, and meansfor actuating the shaft whereby the jaws are caused to engage ordisengage the car wheel, said clamp having means for guiding themovement of the clamp.

6. A car mover comprising a frame,

rollers therefor for riding on a rail, a clamp having a. fixed jaw atone end and a trunnion at the other parallel to the fixed jaw, a jaw onthe trunnion, a rocking shaft on the frame, a link connecting the shaftto the movable jaw, a lug shorter than the crank connecting the shaft tothe fixed jaw, means for rocking the shaft whereby the clamp isactuated, and a boss on the frame for guiding the movement of the clampwhen the same is actuated.

7 A car mover comprising a frame, rollers therefor for riding on a rail,a rocking shaft disposed transversely of the frame, oppositely disposedcranks associated with the shaft, one of said cranks having a socket, alever engaging the socket, a clamp having a fixed jaw and a movable jawsuspended from the frame, a lug extending from the crank having asocket, a link connecting said lug to the fixed jaw of the clamp, meanson said link limiting the movement of the fixed jaw to and from saidlug, a link connecting the second crank to the movable jaw of the clamp,and means for actuating the clamp on its suspension from the frame.
